The dual coding theory proposed by Paivio attempts to give equal weight to verbal and non-verbal processing. Paivio (1986) states: Human cognition is unique in that it has become specialized for dealing simultaneously with language and with nonverbal objects and events.
Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state â¦ . Thus the melting point of graphite is high, same goes for diamonds. Even though it is a covalently bonded compound, these 2 examples are the only ones that have high melting points. The melting point of graphite is 3500 c and 6332 f, specific gravity is 2.25, pounds per cubic inch is .812, 21 people found this useful.
The metal with the highest melting point is Tungsten (W) at 3410 degrees Celsius (6170 degrees Fahrenheit). However, technically Carbon has a higher melting point, though not under normal atmospheric conditions. This is because it sublimates (turns directly from a solid to a gas) at 6740 degrees Fahrenheit under normal circumstances.
